3d printed stunt wrench for the film Moonshot

I was recently commissioned to make a pipe wrench for use in filming Moonshot: A Retro Futuristic Comedy. They needed a wrench for use in a fight scene that wouldn't injure the actors should there be any accidents. I set out to make them a 3d printed pipe wrench that would fit the bill. Here's the final product:



I started by slicing the 3d model I found into several parts and printing them. The parts were glued together using Weld On 3, a solvent cement.

Next I filled the seams with Bondo Glazing Putty and sanded the seams down.



After that, I covered all of the parts in XTC-3d, an epoxy coating. I colored the coating red using a urethane dye to better see the coverage.



And now for much more sanding. To make things faster, I used a power sander and a dremel for the larger concentrations of coating. The dremel was also used to add texture to spots where the wrench would wear down naturally.



A coat of primer to fill the scratches and help paint adhesion



Initial paint coloring, looks a little too new



Now to ruin it. Dry brushing was used to simulate scratches around areas of wear and tear. Black shoe polish was used to add in some grime.




And there we have it, one plastic wrench, complete with weathering
